Image Occlusion Enhanced, Question mask not working


I recently downloaded the newest version of Anki and downloaded the Image Occlusion Enhanced add-on. After making cards using this add-on, the pictures in my deck appear blank with no question masks covering. Only the picture itself with nothing covering it appears when I am studying.

I went under Browse, and in this picture, you can see the question masks that are supposed to be on the cards below:

And this is when I preview that same card:

I have opened anki while holding shift, and this does not resolve the issue. Please let me know if I am doing something wrong or if I should try something else!

Thank you for your time.
